Perturbation studies of excitable media
… is self-organized criticality and the other is periodic forcing and how they can be studied with the BZ reaction. Self-organized criticality is the ability of a system to organize itself into a critical state as a response to random perturbations. Periodic forcing gives rise to waves being …

Investigation of a Spinning Disc as a Thin Film Photocatalytic Reactor for the Degradation of Recalcitrant Wastewaters
… of methylene blue are likely the result of periodic forcing from the peristaltic pump enhancing the adsorption of the oxygen and/or enhanced electron transfer from the catalyst to the oxygen. Adsorption of oxygen and/or electron transfer to the oxygen are often found to be the rate limiting …

Linear and nonlinear Rossby waves in basins both with and without a thin meridional barrier
… sub-basins. Solutions are forced by a steady periodic wind forcing applied over a meridional strip near the eastern side. Bottom friction is present to allow the solutions to reach equilibrium. The linear solution for the basin containing the barrier is determined analytically and the …

Laminated Sediments of Loch Ness, Scotland: Indicators of Holocene Environmental Change
… if patterns of sedimentation may be linked to periodic forcing processes. Cyclicities observed in recent sediments include those of ca 210 and ca 90 years, which are also present in many other climatically-related records. Analysis of lamination thickness in the 'long' cores has proved …

Discrete time crystals beyond the MBL paradigm
… crystals (DTCs) are systems that, subject to a periodic forcing, respond with a period larger than that of the drive. Breaking the discrete time-translational symmetry of the underlying equations, DTCs maintain an infinite autocorrelation time, avoid ergodicity, and realize a novel …

Analysis of a partial differential equation related to pressure-driven separations of binary liquids
… resulting nonlinear, time-dependent, and time-periodically forced partial differential equation, of a type that has received relatively little attention. To better understand the importance of nonlinearity to the underlying physics of pressure-driven diffusion in the context of …

Random perturbations of delay differential equations at the verge of instability and periodically driven nonlinear oscillators
… (chapter 6) deals with random perturbations of periodically driven nonlinear oscillators. The recent surge of research articles in energy harvesting focuses on the cantilever beam devices which are used to convert small amplitude mechanical vibration into an electrical energy source. …
